Type Selection and Layout of Shenzhen Yangangdong Interchange Project

针对城市中多路高快速路网的交叉越来越多的情况,对在路网密集及用地紧张的条件下设计出交通功能齐全的互通立交进行深入探讨[1]。对深圳市盐港东立交工程的立交功能、路网结构及交通量进行分析,并结合场地现状边界条件、地下管网、周围建筑和环境景观等因素进行定性定量分析,合理选择立交型式,使设计既满足使用功能需求,又能达到造型优美、交通组织顺畅、占地规模小的要求,同时还可提升路网的运行效益。

Aiming at more and more crossing situation of multiple expressway network, this paper discusses the multiple traffic functions of interchange designed under the condition of dense road network and limited land, and analyzes the interchange function, road network structure and traffic volume of Shenzhen Yangangdong Interchange Project. Combined with the present boundary conditions of site, the underground pipe network, the surrounding buildings and the environmental landscape, this paper carries out the qualitative and quantitative analysis, and selects the suitable interchange type to make the design not only meet the use function demand, but also achieve the requirements of beautiful shape, smooth traffic organization and small land scale, and also able to upgrade the operation benefit of road network.
